Robust and Ultrasensitive Determination of Hormones and Steroids by LCMSMS Sylvain Lachance, Danielle Lachance, Nadine Boudreau, Sofi Gagnon-Carignan and Ann Lévesque (inVentiv Health Clinical, Québec, Canada) Introduction Results The therapeutic use of hormones and steroids is widely known among the pharmaceutical community. They are used for many indications. More than 200 bioanalytical projects were performed with these assays. Since 2009, over 500000 study samples Contraceptive hormones and hormonal therapy are among the most common use of these compounds. The goal of this work is to were analyzed with these methods. Overall performances were excellent with 99% of the calibration standards demonstrate that the LCMSMS determination of hormones and steroids can be reliable and robust. Extraction method, chromatography (CS) and quality controls (QC) meeting the acceptance criteria. Moreover, the incurred sample reproducibility of conditions, issues encountered, performance of the assay and reproducibility are discussed below for multiple hormones and steroids such these assays was demonstrated with a mean of 98% of the reassays confirming their original values. For most of as estrone, estradiol, ethinyl estradiol, etonogestrel and levonorgestrel. the methods, co-medication interference evaluation was assessed during validation. For complete details of the overall performances by method, please refer to Table 3. Table 3. Overall Performance of the Methods Methods Summary Total Number Percent Total number of Percent Total number of Percent Most of the hormones and steroids are extracted using a liquid-liquid extraction.

For etonogestrel, a derivatization step was done with danzyl chloride to get rid of Study impurities and achieve the required sensitivity as etonogestrel cannot be derivatized.
